DETACHABLE HEEL SPECIFICATION forming part Of Letters Patent N 0. 723,754, dated. March 24, 1903.

Application filed July 18,1902.

T0 ctZZ whom it may concern:

Be it known that we, MICHAEL H. SULLI- VAN, GEORGE J. DIXON, and J OHN W. WHITE, citizens of the United States, residing at Oarbondale, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Detachable Heel, of which the following is a specification.

The invention relates to improvements in detachable heels.

The object of the present invention is to improve the construction of detachable heels, more especially the means for detachably interlocking a heel with a boot or shoe, and to provide a simple, inexpensive, and efficient device of great strength and durability, adapted to be readily applied to a shoe and capable of enabling a heel to be quickly attached to and removed from the shoe to permit a heel to be renewed or to enable different kinds of heels to be used or for any other purpose.

The invention consists in the construction and novel combination and arrangementof parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a longitudinal sectional view of a portion of a shoe provided with a detachable heel constructed in accordance with this invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a detail view of the plate or section which is attached to the shoe. Fig. 4 is a similar view of the plate or section which is carried by the heel.

. Like numerals of reference designate corresponding partsin all the figures of the drawings.

1 designates an upper plate or section which is an gularly bent at opposite sides of the center to form a tapering dovetailed groove 2, and the latter tapers both longitudinally of the shoe, as clearly illustrated-in Fig. 3 of the drawings, and is also tapered vertically, being provided at opposite sides of it with inclined walls 3. The upper or heel plate, which is provided with side flanges 4 at opposite sides of the tapering dovetailed groove, is secured to the sole 5 of a shoe 6, which may style or pattern and which be of any desired are No. 116,110. on model.)

is preferably provided at its heel portion with a suitable lift 7 to receive the fixed upper section or plate. The lift 7 is recessed to form a seat for the upper fixed section or plate, which tapers rearwardly at its grooved or bent portion, and it is secured to the shoe by means of screws or other suitable fastening devices, as clearly illustrated in Fig. 2 of the drawings.

The upper or fixed section forms a way for a lower removable plate or section 8, which is detachably interlocked with the said upper section and which is secured to aheel 9. The plate 8 is angularly bent similar to the upper plate and it forms a taperingdovetailed tongue 10, extending upward from the heel and provided with inclined side walls 11, presenting inclined outer faces. The tapering dovetailed tongue forms awedge and when introduced into the dovetailed groove fits snugly and firmly therein and is securely held against lateral movement. The lower heel plate or section is provided with side flanges 12,which are perforated for the reception of screws or other suitable fastening devices for securing them to the heel 8. The side flanges 12 are secured to the upper face of the heel in shal low recesses thereof, and the tapering or wedge-shaped tongue projects above the heel to interlock with the upperstationary plate or section.

The lower heel plate or section is locked against longitudinal movement by a transversely-disposed key or bolt 13, having its engaging end arranged to extend through an opening 14 of the side wall of the lower plate or section for engaging a similar opening 15 of the stationary upper plate or section, which openings are adapted to register when the plates or sections are assembled in proper position. The bolt or key is held in its engaging position by means of a spring 16 of approximately U shape,having a short side 17 and an extended or long side 18, which passes through a recess 19 of the key or bolt and which terminates at the edge of the heel, whereby it is arranged within convenient position to enable the bolt on key to be readily operated. The bend of the spring is located within the-groove of the plate 8, and the short side 17 is curved adjacent to its end and the latter projects into a perforation 20, whereby the spring is held against longitudinal movement. When the parts are assembled, the key cannot become displaced in operatingit, as it is of a length slightly greater than the width of the groove of the heel plate or section, so that it will extend slightly into the opening 14:. The spring is adapted to be readily operated to lock and release the plates or sections and the heel and the latter may be removed and replaced as desired. This construction will enable worn heels to be renewed and will also admit of different styles of heels to be readily applied to a shoe and will enable the style of heel to be changed when desired.

The plates or sections 1 and 8 may have their relative positions changed, the device being reversed and the plate or section 1 being attached to the shoe instead of to the heel and the plate or section 8 being applied to the heel. As this change is perfectly obvious and does notinvolve any change of construction, illustration thereof is deemed unnecessary, and we desire it to be understood that changes in the form, proportion, and minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

hat we claim is- 1. A device of the class described comprising two plates or sections designed to be seadjacent plate or section, substantially as described.

2. A device of the class described comprising two plates or sections, angularly bent at opposite sides to form dovetailed portions adapted to interlock with each other, said dovetailed portions being provided with registering openings, a transverse key or bolt arranged on one of the plates or sections and adapted to extend into the said openings, and a spring connected with the key or bolt and having an inner loop engaging the plate or section on which the key or bolt is mounted, said spring being also extended to form a bandle, substantially as described.

In testimony that We claim the foregoing as our own we have hereto affixed our signatures in the presence of twowitnesses.
